CHARLES Gr. SANDERS, OF INDIANAPOLIS, INDIANA.

SOFT-DRINK SHAKER.

Application filed June 25, 1924. Serial No. 722,392.

To all whom it may concern:

Be it known that 1, CHARLES G. SANDERS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Soft-Drink Shakers, of which the following is a specification.

My invention relates to an improvement in means for shaking and thereby mixing soft drinks, formerly done by hand, which process when so performed was a time-consuming and laborious job to accomplish the proper results. My soft drink shaker may be set in operation and the drink dispenser occupy himself with other duties during the mixing process. Its rapidly reciprocating motion with the operating mechanism concealed below the counter creates an attractive display as well as being a labor saving device which mixes the drinks much more thoroughly than can be accomplished by hand or by the common mechanical stirrer.

A further object of my invention is to provide means for receiving and securing within the shaker tumblers of varying heights. The drink is served in the tumbler or glass in which it is mixed and consequently different glasses are employed, the heights of which may vary slightly even in the same indicated size of the glasses.

I accomplish these and such other objects as may become apparent in the following description by the means as shown in the accompanying drawing, in which- Fig. 1 is a front, vertical elevation of my shaker with fragments removed from the shaker head, top strap, and counter top, to show more clearly the height adjusting means, and the means of securing the shaker to the. counter; Fig. 2, a side elevation of my shaker, showing the head raised through a quarter of a turn of the shaft, and having fragments of the standard and head rod removed; Fig. 8, a vertical section of the cap taken on the line 3-3 in Fig. 1; and l a, a top plan view of the head taken on the line H in Fig. 1.

Like characters of reference indicate like parts throughout the several views.

Referring to the drawing, I form a standard 5 with a horizontal flange 6 adapted-to be secured to the underside of a table or counter top 7 by the screws 8 or similar means and having a pilot 9 extending through and flush with the top side of the top 7. The lower end of the standard 5 is transversely bored through to receive the main shaft 10, on one end of which is rigidly secured a flywheel 11 acting also as a drive wheel. The standard has the lower end bifurcated at right angles to the main shaft so as to permit the cam 12 to be received within the standard bifurcation as the shaft 10 is inserted through standard ends, and the shaft 10 is there secured against horizontal displacement by securing the cam 12 to the shaft 10 by placing a pin 13 through a hub 1d the cam and through the shaft 10.

Surrounding the cam 12 is the integral eccentric strap 15 with the extending connecting rod 16 which slidingly fits within the bifurcation of the standard 5 and is pivotally connected by a cross pin 17 to the head rod 18 sliding vertically within the central channel 19 bored through the standard It will be noted in referring to Fig. 2, that the connecting rod 16' is attached to the head rod 18 at a distance up from the lower end so as to secure a maximum bearing surface for the head rod 18, and that the head rod 18 has its lower end accordingly bifurcated to straddle the connecting rod 16.

The head rod 18 is preferably made hol low and receives in its upper end the lug depending from the head 20 and the head 20 is thereby secured to the head rod 18 by placing t pin transversely through the head rod 18 and the contained lug as shown by dotted lines in Figs. 1 and The head 20 has its upper side cup-shaped to receive the base of a tumbler or glass 21, and to one point on the circumference of the head 20. I attach a cap strap 22 preferably made of spring steel, by forming a vertical slot in the head the width and depth of the strap, inserting a screw 23 through a'vert-ical slot 2% in the strap 22 and entering the screw into the head and drawing the cap strap 22 up in the slot by tightening up the screw 23. The upper end of the cap strap 22 is formed into an eye to receive the pin 25 pivotally securing the cap 26 to the cap strap 22 in the manner of a hinge.

Diametrically opposite the ca strap 22, is a similar cap strap 27 secured to the head 20 in the same manner as the strap 22, but having its upper end slightly curved outward and a hole 218 drilled therethrough to ward sufficiently, the pin 29 is released and the cap 26 may be swung up and backwardly out of the way so as to permit re-.

moval of the tumbler 21.

In order to secure a watertight joint be:

tween the cap 26 and the tumbler 21, I form an annular groove from the inside of the lower rim ofthe cap to receive a soft rubber gasket 30 which bears directly on the rim of the tumbler and which is compressed as the cap 26 is pressed down to permit the pin 29 to engage in the hole 28 in the strap 27.

Both straps 22 and 2? have inturnedlower ends 31 and respectively, against the top sides of which, bear the adjusting screws 33' passing vertically through the head 20 and being adapted to be adjusted from the upper side of the head 20. The cap 26 is suitable spaced apart from. the head 20 to the required tumbler height, by loosening the screws and slipping the straps 22 and 27 upior down as required \=.'it l1in the limits or'the slots and turning the adjusting screws 33 down to contact firmly against the strap ends 31 and so as to prevent any upward displacement of the straps 22 and 2'? when the cap pressed into place over the tumbler, and

the side screws 23 are then drawn up tghtly.

To operate my device, I employ the 601114 mon and well known type of fractional horse-power electric motor such as is used in driving a sewing machine, and so mount the motoras to have its drive pulley iir roihngcontactwith the fly wheel 11 and so operate the mechanism of my shaker. However, any other driving means may be employed and the wheel changed to suit the means. The operation of my shaker consists in )lacinn; the 3Y0 oer in redients withr in the tumbler, as sugar, lemon juice, water and ice for a lemonade drink, placing the tumbler in the head 20, closing the cap 26 over the tumbler, and'switching on the mo tor, whereupon the tumbler will be rapidly reciprocated by means of the reciprocating mechanism ashereinbel ore described. The cap 26, being cone shaped within, materially serves to cut, mix, and agitate the ingredients of the drink as is essential for the 16th day oi June, 1924.

best results.

Having fully described my invention in the form now best known to me, what claim and desire to secure by United States Letters Patent is:

1. In a soft drink shaker, means adapted to give vertical reciprocating motion to a head, adapted to receive a tumbler, a cap on said tumbler, a strap hinged to said cap by its upper end and adjustably engaged by its lower end to said head, a second strap adjustably engaged by its lower end to said head and detachably engaging said cap by its upper end.

2. In a soft drink shaker, a head having an upper surface cupped to receive the base of a tumbler and being secured to means adapted to give a vertical reciprocating motion to said head, a conical cap having asortt gasket retained in an annular groove in the base of the cap, said gasket being interposed between the top rim of the turnbler and the cap, a strap hinged by its upper end to one side of said cap and having its lower end formed tocontact saidhead within a verticalsiot formed on the side of said head, said strap having a central vertical slot cut through the strap at said contact 'ith the head and said strap having its lower end further depended and thence turned horizontally inward, a secondstrap elastically and detachably engaging said cap by its upper endand formed to contact near its, lower end within a slot formed in the side or said head, said second strap having a central vertical slot cutthrough the strap at said contact, and said second strap having its lower end further depended and thence turned horizontally inward, horizontal screws passing through the slots in saidi'irst and second straps adapted to retain said straps in contact with said head by heads on said screws contacting said straps as said screws are screw threadedly engaged and drawn up in said head, and adjusting screws vertically passing through said headand contacting each ofthe horizontally inturned ends of saidtirst and sec ond straps, V

3.
